Hi Krakenites!(Krakenzens, Krakeners, etc) Can the Kraken's heater cartridges be run at 24V? I don't see any linear rail connections on the Kraken itself. Am I missing it or is it not on the part itself? Can anyone recommend a good Kraken direct drive mount? I saw this one: http://coherent-reprap.blogspot.co.uk/ which I like because it's direct drive Though it looks kind of annoying to modify the gcode for that. I'm planning on potentially doing some flexible filaments like Ninjaflex. How large of a water reservoir is recommended for bulletproof operation? Is there an ambient temperature at which the water doesn't transfer enough heat? I'm planning on having the water run through a heated enclosure, I assume that water's high thermal insulation will keep it from becoming ineffective.
